Scientists at the Salamanca Cancer Research Center (CIC) (Spain) have used the CRISPR-Cas9 gene-editing technique to eliminate the oncogene that produces chronic myeloid leukemia. In an article published by the Oncotarget magazine they show that in this way the tumor mouse cells revert to their normal state. If researchers can reproduce the results with patient cells, they would have an effective tool to treat the disease.Extract of La edición de genes permite revertir células de leucemia mieloide crónica a su estado normal
